NIPSCO to upgrade electrical transmission

MICHIGAN CITY — NIPSCO on Friday announced the first phase of a long-term project to upgrade portions of its electric transmission system in northwest La Porte County, beginning in Michigan City, to support future system reliability for customers.

The upgrade includes retiring 52 existing electric transmission lattice towers and converting them to steel monopole towers, installing nine miles of new electric transmission line within existing pathways, and new energy conductors to provide greater capacity to the system, according to NIPSCO.

The project will begin construction on Monday, Oct. 21, and is expected to last until May 2020. Crews will be working Monday-Saturday from 7 a.m. to 6 p.m., and possibly weekends and evenings to honor project deadlines.

Construction will take place in the existing rights-of-way between the Michigan City Generating Station and the Bosserman Electric Substation on Ind. 39 just south of the Michigan state line.

Michels Corporation, an approved NIPSCO contractor, will be supporting the planned work, and area residents and businesses may experience additional truck traffic in the area and lane and road closures, the utility said. Signs and detour routes will be posted ahead of time, and flaggers will be on site directing traffic during construction hours.

There are no anticipated service interruptions with this project, according to NIPSCO

NIPSCO said it will continue to work with Michigan City and La Porte County officials to minimize impact to customers in this area.

Similar reliability projects to support NIPSCO’s electric generation transition plan will be announced in the future, according to the utility.
